The state provides several methods to facilitate your search, ensuring you can find the necessary information about any LLC registered within its jurisdiction.

These methods include:

1. Using the Secretary of State's Website

The Secretary of State's website is the primary resource for conducting an LLC search in Louisiana.

  1. Visit the Louisiana Secretary of State's website and navigate to the "Business Services" tab.
  2. Select "Search Business Filings" from the available options.

  4. Click the search button or press enter to initiate the search.
  5. If you chose search by "Entity Name" review the search results. If your desired business name appears as a result, it means it is available for use.

By performing this simple business name search, you can determine the availability of your preferred LLC name and proceed with the next steps of starting your business in Louisiana.

You can perform an LLC search on the Secretary of State's website by:

This is the most common method to find LLCs in Louisiana. Enter the name of the business you want in the search bar on Louisiana's business entity search website.

Once you locate the desired LLC, click the "Details" button to access more information about the company.

b. Search by Charter Number/Trade Registration Number/Reservation Number

If you can access the business's charter, trade registration, or reservation numbers, you can utilize the search function on the Secretary of State's commercial search webpage.

Enter the relevant reservation number and navigate to find the specific LLC you want.

c. Search by Registered Agent

Another way to look up an LLC in Louisiana is by searching for a Louisiana registered agent. A registered agent is an individual or business that agrees to receive legal documents on behalf of the LLC.

On the Secretary of State's website, click the "Registered Agent" tab on the commercial search webpage.

From there, you can search for the desired registered agent and access further details by clicking the "Details" button.

Utilizing these different search options allows you to find and gather the necessary information about an LLC in Louisiana.

According to the article, businesses leveraging these tools have seen a significant increase in engagement, with social media driving up to 30% of traffic to websites, showcasing the power of these platforms in enhancing digital visibility.

In addition to the official state resources, here are five alternative methods to search for an LLC in Louisiana:

  • Business Directories: Websites like Yelp, Better Business Bureau, and industry-specific directories can offer information and reviews on LLCs.
  • Legal Databases: Platforms like LexisNexis or Westlaw can provide legal information on LLCs, including litigation history.

How to Check If A Business Name Is Trademarked in Louisiana?

To check if a business name is trademarked in Louisiana, search the US Patent and Trademark Office (USPTO) website. This search will reveal if the name is federally trademarked.

Also, checking with the Louisiana Secretary of State can help identify state-level trademarks.

Here's how to proceed:

1. Use the Federal Trademark Search (US Patent and Trademark Office (USPTO) Website)

The first step is to visit the USPTO's official website and use the Trademark Electronic Search System (TESS).

This database includes all registered trademarks and pending applications at the federal level.

Searching here will help you identify if your desired business name or a similar one is already trademarked, potentially leading to legal issues or rejection of your trademark application.

For state-level trademarks, you should check with the Louisiana Secretary of State.

Louisiana provides resources for searching business entities and registered trademarks within the state.

Visit the Louisiana Secretary of State's business search page. This search primarily identifies business entities rather than trademarks.

According to the Louisiana Secretary of State's annual report, in 2023, the business search tool facilitated over 50,000 searches, underscoring its utility in navigating state-level business registrations and trademark inquiries.

But it's crucial to ensure that another business does not already use your desired name in a similar capacity, which could also lead to trademark conflicts.

3. Consultation with a Trademark Attorney

Given the complexities of trademark law and the potential for overlap between state and federal registrations, consulting with a trademark attorney can provide valuable insights and guidance.

An attorney can help you navigate the search process, interpret results, and advise on the likelihood of trademark registration success.

The main purpose of looking up an LLC in Louisiana is to determine if the business name you want to use is available for your company.

You can also lookup an LLC to:

  • Verify the legal status of an LLC.
  • Gather information about the LLC's registered agent.
  • Understand the business's history and compliance status.
  • Check for any potential legal issues or litigation.
  • Conduct due diligence before making business decisions.
  • Assess the competition within a specific industry.
  • Check a business before completing a deal to ensure transparency and trust.
